In response to compile breakage introduced by a series that added the
pud_write helper to x86, Stephen notes:
did you consider using the other paradigm:
In arch include files:
#define pud_write pud_write
static inline int pud_write(pud_t pud)
.....
Then in include/asm-generic/pgtable.h:
#ifndef pud_write
tatic inline int pud_write(pud_t pud)
{
....
}
#endif
If you had, then the powerpc code would have worked ... ;-) and many
of the other interfaces in include/asm-generic/pgtable.h are
protected that way ...
Given that some architecture already define pmd_write() as a macro, it's
a net reduction to drop the definition of __HAVE_ARCH_PMD_WRITE.
